SPF, which is an acronym for Sender Policy Framework, is an e-mail security system, that is designed to verify if an email message is sent by an official server. Employing SPF protection for a particular domain name will stop the counterfeiting of emails made with the domain. In simple words: enabling this attribute for a domain name generates a specific record in the Domain Name System (DNS) containing the IP addresses of the servers which are permitted to send email messages from mail boxes using the domain. The moment this record propagates globally, it will exist on all the DNS servers that route the Internet traffic. Any time a new email message is sent, the first DNS server it uses checks if it originates from an accredited server. If it does, it's sent to the destination address, however if it doesn't originate from a server part of the SPF record for the domain, it is rejected. In this way nobody will be able to mask an email address to make it appear as if you're e-mailing spam messages. This technique is also referred to as email spoofing.

SPF Protection in Cloud Web Hosting

If you host your domain names in a cloud web hosting account on our end and we handle the e-mail addresses for them, you are able to activate SPF protection for them with a couple of clicks inside your Hepsia Control Panel. The service can be found in a section of its own where you are able to view which domains are already protected. For those that are not, you will be able to enable the SPF protection option and manage a variety of things in the process - the hostnames of the mail servers that are allowed to send messages from your e-mails, the IPv4 and IPv6 addresses of the servers, as well as to set a rule that email messages can be sent only when your domain names have our MX records. The aforementioned choice is the most secure one, but it can be used when we take care of the emails for your domains and you are not using a different e-mail service provider. The new records will propagate within 1 day and nobody will be able to forge the FROM field in an email by using your email addresses.

SPF Protection in Semi-dedicated Servers

When you have a semi-dedicated server account from our company, you will be able to protect your email addresses by enabling the SPF protection service for every domain name in your account with only a few mouse-clicks. You can do this in the Emails section of the Hepsia Control Panel which comes with the semi-dedicated accounts and even in case you have no previous experience with such issues, you won't have any troubles to activate the security. The only things that you will need to do is to choose a domain name from a drop-down menu then type the mail server hostname and IPv4 or IPv6 address. As soon as the updated record propagates, messages from your email addresses will be mailed worldwide only if they were sent from that server. In case your emails are taken care of by our company and not by some third-party supplier, you'll also be able to use an option for emails to be sent only if the domain name contains our MX records and this is the most secure option. In case you have any kind of questions regarding thisfunction, you'll be able to get in touch with our technical support team 24/7.
